The apartment was at a very good location. It is near Saphan Taksin(S6) BTS station which is about a 7 min walk from the building. This particular BTS station is also near Sathorn/Central pier where you can ride a boat to many of the temples like Wat Pho, Wat Arun and the Grand Palace. The apartment also has some shops and restaurants nearby like 7-11, McDonald's, Starbucks (which is at the building itself), etc. On your way to the building from the BTS station, you will also pass by a lot of street food! So you have options for food when you get hungry.
As for the apartment itself, it looks exactly like the pictures provided by Narn. I really like the design of the place, very minimalist and modern. And it is very spacious. Narn provided all the necessities like towels, an iron, hairdryer, etc. All in all, it made for a very comfortable stay.
Narn was kind enough to answer all our queries though I wasn't able to meet him in person. But he was responsive and very nice. Overall, an enjoyable stay! Would definitely recommend his place.
